This invention relates to suspension clamps.

Objects of this invention are to provide a novel form of suspension clamp which has a minimum number of parts, which is so constructed that a single U-bolt performs the dual function of both supporting the body portion of the clamp and also of holding the two portions of the clamp together.

Further objects are to provide a suspension clamp which may be made with the utmost cheapness, which is of very strong construction, which is compact, and which is easy to assemble and disassemble.

vAn embodiment of the invention is shown in the-accompanying drawings, in which:

Figure 1 is a view showing the clamp in place supported by one form of support or suspension member.

Figure 2 is a side elevation of the clamp drawn to anenlarged scale and with parts broken away.

Figure 3 is a plan view of the clamp. Figure 4 is an end elevation of the clamp with parts broken away.

I Referring to the drawings, it will be seen that the clamp consists of a main body portion 1, which is provided with downturned ends 2, and which has a channeled or groove upper portion 3 within which the cable 4 is carried, the cable extending to any suitable device.

* The clamp is provided with an auxiliary member 5, which is provided with a slightly 6 directed towards the channeled face 3 of the main body portion. This auxiliary member 5 is also provided with an exterior channel 7 extending transversely o the auxiliary member, as shown most clearly in Figure 3. This outer channel receives the arched portion of the U-bolt 8. The arms of the U-bolt extend through apertured ears or lugs 9 formed integrally with the main body ort1on The ends of the U- i: the clamping nuts 10, preferably split washers 11 being interposed between he nuts 10 and the ears 9, as

shown in Figures 2; and 4.

The central portion 'of the auxiliary memas indicated at 12in Figure 4, soasto receive the supporting member 13,

by means of which-the clamp is su ended. The supporting member 13 may ta e any form and in reality forms no portion of this invention. In the form shown merely for the purpose of illustration support has been used. Whatever type of support is used, the supporting member cor responding to the member 13 passes through the aperture 120i the auxiliary member 5 and thus loops through the U-bolt 8, so that the supporting member 13 directlysupports the suspension clamp through the medium of the U-bolt.

In using the clamp it will be readily apparent that it is a very simple matter to position the cable 4 within the channel 3 of the bodyportion 1, and thereafter position auxiliary member 5 in contact with the cable 4. The U-bolt is'then slipped into place and the nuts 10 screwed upon the ends or armsof the U-bolt, thus drawing the auxiliary member 5 towards the main or body portion 1, and thereby clamping the cable ti member 5.

It is to be noted from reference to Fi re 2 that there is no chance of cuttingzor means of the clamp, cable is received in the channeled portions of the clamp, and as the ends of the body portion 1 are rounded, the ends of the auxiliary member 5 being also rounded .as indicated at 14 in Figure 2.

It will be seen that the, clamp consists essentially of only three main parts, namely, the body portion 1, the auxiliary member 5,

f and the U-bolt 8. Also that these three parts an insulator type of ghtly be-- tween the body portion 1 and the auxiliary as the the are of very sim leshape and'may be most The suspension clamp, therefore, may be very cheaply produced.

It is to be noted further that theU-bolt performs the double function of holding the parts'of the clamp in firm engagement with the cable and also of supporting the suspen-' sion clamp.

Further thanthis, it is obvious that the pressure rial portion of the cable, and thus there is no chance of cutting the cable.

applied by the clamp to the cable is not localized, but is distributed over a mate LGWAQE f T U-bolt, said auxiliary member having a notch formed in the laterally extending portion for the reception of a In testimony wh inventor is afixed It tive rather than limiting, as the invention I may be variously embodied and is to be inter prcted as claimed.

1' claim: l. A suspension clamp comprisin a body 13 portion and an auxiliary portion adapted to receive between them acable, and a U-bolt for drawing said body portion and auxiliary member towards each other to clamp the cable, said U-bolt having a portion adapted to be engaged by a support, and said auxiliary member being provided with means iacilitating the engagement of said ll bolt'by a support whereby the clamp is held in clamped position and supported by said U-bolt.

2. A suspension clamp adapted to receive a cable and comprising a channeled body ortion within which the cable is adapted to t, an auxiliary member cooperating with said body portion to hold said cable in place, said auxiliary member having a channel at right-angles to said first mentioned channel, and a U-bolt positioned within said last mentioned channel and having its ends passing through said body portion, said auxiliary member having a cut out across which said ll-bolt extends.

3. A suspension clamp adapted to receive a cable comprising a body portion havin a longitudinally extending channel and having a pair of laterally projecting apertured ears, an auxiliary member having a portion adapted to clamp the cable within the channel of said body portion and having a laterally extending channeled portion, a U-bolt having a curved yoke portion seated Within said last .mentioned channeled portion and havin its arms projecting through the apertureg ears of said body portion, and nuts screwed upon the arms of said U-bolt, said auxiliary member having an aperture beneath the curved portion of said U-bolt.

4. A suspension clamp comprising a body portion having a, longitudinally extending channeled part provided with outward turned ends and having laterally projecting apertured ears, an auxiliary member having a longitudinally extending portion located opposite the longitudinally extending part of the body portion, said auxiliary member having a laterally extending portion provided with a curved channel, a U-bolt having a curved yoke portion seated within the curved channel and having its arms projectingthrough'the apertured ears of said body portion,'and nuts screwed upon the arms of said support.
